Application led February 21, 1928. Serialv N'o. 255,966.

This invention relates to awning arms and more particularly to a laterally swinging folding awning arm.

An important object of the invention is to provide a device of this character which will permit of a wide range of adjustment and which will accordingly materially reduce the number of sizes of awning arms which must be kept in stock by the manufacturer.

A still further object of the invention is to provide a device of this character which may be very readily adjusted not only as to length but as to the angle which it occupies with regard to the support from which it extends and which will enable a proper alignment of the supported awning when the points of attachment of the awning arms may not be made at the same level.

A further object of the invention is to provide in a device of this character a construction such that the elbows of the arms may be disposed at the same level when folded.

A still further object of the invention is to provide a device of this character which may be readily and cheaply manufactured and which will be durable and efficient in service.

These and other objects I attain by the construction shown in the accompanying drawing, wherein Jfor the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a side elevation showing an awning arm constructed in accordance with my invention;

Figure 2 is an enlarged elevation partially in section of the shoulder casting;

Figure 3 is an end elevation of the shoulder casting;

Figure 4 is a section on the line 4 1 of Figure 2.

Referring now more particularly to the 45 drawings, the awning arm comprises an upper arm section 10, a shoulder casting l1 to which the upper end of the upper arm section is secured, a lower arm section 12, which is connected with the upper arm section by 50 an elbow joint 13 and an awning pole holder 14 secured to the outer end of the lower arm section.

The shoulder assembly consists of three main parts, a casting 15 adapted to be secured against the building to which the awning is to be secured, a U-shaped support 16 and an upper arm fitting 17. The casting 15 embodies a wall 18 adapted to extend perpendicularly to the supporting wall to which the casing is fastened and having an opening 19 formed therein. Throughthis opening 19 is extended a pivot bolt 20, which extends through the connection between the arms of the U-shaped support 16. The arms 17 of this Ufshaped support have aligned openings'21 for the passage of a pivot bolt 22 which extends through ears 23 formed upon the fitting 17. The outer end of the wall 18 has a flange 241A throughwhich are directed set-screws 25 engaging the U-shaped support at opposite sides of the pivot bolt 20, solthat they may be operated toadjust the angle of this Ushaped support to the vertical and accordingly the angle of'the fitting 17 and portions attached thereto. 75

Theiitting 17 rhas secured thereto a` pair oi parallel bars 26 which are providedy with spaced perforations 27. The adjacent section 28 ot the elbow joint 13 has secured thereto a pair ot tubes 29 telescopically receiving the bars 27 and having securing ele# ments 30 for passage through selected open ings 27, so that the length of the upper arm section 10 may be regulated. The remaining section 30 of the elbow joint which is con- 85 nected to the section 28 by the usual pivot bolt 31 has secured thereto a bar 32 similar to the bars 26 and which telescopically engages a tube 33 secured to the awning pole holder. It will be ob-vious that with a device of this character, the supporting casting 15 of the shoulder assembly may be attached at any point within reasonable limits and the arm adjusted, so that it will support the outer edge of the awning at the proper level. The upper arm may then be adjusted so that the elbows 13 are at the same level when folded and the lower arm section 12 adjusted to its proper length to insure the proper extension of the awning. All of these adjustments may we be made unassisted by a single Workman, so that the awning arm is not only capable of a greater range of adjustment, but may be more cheaply, rapidly and accurately installed than the ordinary type of arm. It will be obvious that the arrangement of the adjustable sections of the upper and lower arm portions may be Varied to a considerable extent. For example, the positions of the bars and tubes might be reversed and tubular elements might be employed instead of the bars. Y

Since the construction hereinbefore set forth is capable of a certain range of change and modification without materially depart-` ing from the spirit of the invention, I do not limit myself to such specic structure except as hereinafter claimed.

l. In a laterally foldable awning arm structure, upper and lower arm sections connected at their adjacent ends by an elbow joint, ashoulder casting including an outstanding wall, a. pivot extended therethrough, a U-shaped support rotatably adjustable upon the pivot, a second pivot carried by the arms of the support and substantially paralleling said wall, an upper arm fitting mounted upon the last named pivot, the outer end of said wall having a flange and set-screws extended through said flange to engage the U-shaped support at opposite sides of 1tlhepiyot connecting the same with the wa l 2. In a` laterally foldable 4awning arm structure, upper and lower arm sections connected at their adjacent ends by an elbow joint. asshoulder casting including an outstanding wall provided at its outer edge with a flange, a \U-sh'aped support having its cross bar pivoted to said outstanding wall to swing ina plane paralleling the same, a pivot `connecting the arms ofthe U-shaped support and to which the upper arm section is connected,

and means directed through said flange and engaging the cross bar at opposite sides of said pivot for holding the U-shaped support in rotatably adjusted positions.

In testimony whereof I hereunto afx my signature.
